“Second thoughts on Russians…”
Russians seem to do really well with the cold. While they may be better with mites, I haven’t had problems with mites on any colonies while using a sound mite control regimen. The mites are still there, but are manageable. At the end of the day, I wouldn’t base my choice of genetics on how hot someone’s bees get in a YouTube video. If the genetics will keep your girls alive over winter, everything else can be managed for, even if you need to wear the equivalent of armor late in the season.
My situation, thoughts on breeds, and a little bit about how I manage:
I don’t think there’s much to worry about with respect to breed. I’ve kept italians, carnies, saskatrazz, and Russians. I’ve found the same hive, regardless of genetics, can be delightfully docile to downright evil! Even the Russians are nice most of the time.
Docile times… calm wind, neither cool nor hot, nectar flowing, smaller than larger colony, girls are out and about.
Evil times… largely the opposite of above.
I live in northern Michigan where spring comes late and fall comes early. Round about mid-late June, the hives will be big and everything will be in bloom to the point that a strong hive can put in 5-10 lbs of nectar per day. Nectar can come in fast enough that a ripened frame is really rare until after the flow stops. Mid August, the hives can be huge and things largely dry up. If I’m lucky, boxes will be fully ripened by mid September. This, of course, is when we start getting frost.
The point… I - can’t - take honey until very late in the season when my hives are huge, there’s nothing coming in, and the nights/days are cold. Of course, the girls are all cooped up and pissy. I’ve had colonies where I need welding gloves with duct tape to seal them to my suit. I usually wear gaiters. Failure to do either results in bees tunneling into my gloves/boots. The bees on the guys veil in the video? Ha! That was cute! Weren’t nuthin but a thing. My harvesting experience… not fun. (I’m convinced the girls know that they’ll need those stores through May (nearly 8 mos) Fighting to the death is a no-brainer for them when I steal their Honey in the fall.)
All that, coupled with losing more than half of my hives to starvation two winters ago, has made made me adapt my management technique to leave everything on the hives until spring. I just removed the supers last week. The bees didn’t care. The weather was nice.
